A small storm often accompanied by heavy precipitation and frequent thunder and lightning.
What is a thunderstorm.
100
Draw the symbol of a cold front.
What is (triangles on one side only).
100
What type of pressure is in a cyclone?
What is low pressure.
200
Where a continental air mass forms.
What is over land.
200
The type of front involving a fast moving cold air mass that runs into and moves under a slowly moving warm air mass.
What is a cold front.
200
If you are indoors, where is the safest place to be during a tornado?
What is in the basement of a well built building.
200
What technology has helped the National Weather Service to compile daily weather information and to prepare weather forecasts across the country?
What is computers.
200
How does air move in an anticyclone in the Northern hemisphere?
What is clockwise, down, and out.
300
Cold air masses that form north of 50 degrees north latitude and south of 50 degrees south latitude.
What is polar air masses.
300
Explain the movement of air in a warm front.
What is a fast-moving warm air mass overtakes a slowly moving cold air mass.
300
Explain what causes thunder.
What is a lightning bolt can heat the air around it hotter than the surface of the sun. The rapidly heated air expands suddenly and explosively. The thunder is the sound of the explosion.
300
Draw the symbol for a stationary front.
What is (alternating triangles and semi-circles on opposite sides of the line)
300
What type of weather do cyclones bring?
What is unfavorable weather (clouds, wind, precipitation, possible storms).
400
Which two air masses often meet to form hazardous conditions in tornado alley?
What is maritime tropical and continental polar.
400
Which wind belt moves air masses in the United States?
What is the prevailing westerlies.
400
How long do you have to evacuate if a hurricane warning is issued?
What is 24 hours.
400
Lines joining plaves on the map that have the same air pressure.
What is isobars.
400
Where are weather balloons placed in the atmosphere?
What is between the upper troposphere and lower stratosphere.
500
If an air mass is cold and humid, what is it's name and where did it most likely form?
What is maritime polar, formed over oceans near the north or south pole.
500
What type of weather does a stationary front bring to an area? Explain why.
What is a stationary front stalled over an area can bring several days of clouds and precipitation. Where the warm air mass meets the cold air mass, water vapor condenses to form clouds and possible precipitation.
500
Explain how hurricanes gain energy.
What is a hurricane draws its energy from the warm, humid air at the ocean's surface. The more heat and moisture the hurricane picks up, the larger and faster the hurricane becomes.
500
Draw a "weather flag" and describe what direction the wind is coming FROM in your symbol.
What is (the direction the flag is pointing is the direction the wind is coming FROM).
500
If isobars on a weather map are placed very close to one another in an area, describe the weather conditions in that area.
